Igor,
I meant to reply to the group to let them know that the problem had been
solved, but your email makes me think that it has not been solved
fully. The script runs as user backuppc and apparently user backuppc
did not have permission to write to the data locations. Once I fixed
the permissions issue, the command start stop command would work and
give me an "ok."
What makes me think that the problem has not been solved fully is that
when I run the first two of your commands, I get no response (as
expected) and the testgram is created properly. However, your third
command does gives me an error that I don't understand. Below are the
results:
backuppc@linux-pc5:/data/BackupPC/pc$ touch /data/BackupPC/pc/testgram
backuppc@linux-pc5:/data/BackupPC/pc$
backuppc@linux-pc5:/$ ln /data/BackupPC/pc/testgram /data/BackupPC/cpool
backuppc@linux-pc5:/$
backuppc@linux-pc5:/$ rm /data/BackupPC/pc/testgram /data/BackupPC/cpool
rm: cannot remove ‘/data/BackupPC/cpool’: Is a directory
backuppc@linux-pc5:/$ ls -ld /data

tune2fs 1.42.12 (29-Aug-2014)
tune2fs: Permission denied while trying to open /dev/mapper/dreux-root
Couldn't find valid filesystem superblock.
Is the output what was to be expected? A couple of things are throwing
me for a loop. First, on the remove command "rm
/data/BackupPC/pc/testgram /data/BackupPC/cpool", should that really be
"rm /data/BackupPC/pc/testgram /data/BackupPC/cpool/testgram" and is
that the nature of the Is a directory error? I presume so. Or should
my merely removing the linked target also remove the linked file?
Second, the "could not find valid filesystem superblock error is unclear.
Thanks in advance.
